Batch Distillation Column Operation & Controls

Leave a Comment / Heterogeneous Stuff / K Mehra

We can find batch distillation column in almost every chemical process industry. Specially, you can find it more in fine chemicals, specialty chemicals, pharmaceutical and small-scale chemicals production industries. This is so because, batch distillation column requires lower fixed cost and provide higher operational flexibilities. However, batch distillation columns consume more energy than a continuous […]

Boiler Efficiency Improvement

Leave a Comment / Industry / K Mehra

Boilers are the source of energy in form of steam, electricity or both for industries. They supply steam for various heating requirements of the plant. Moreover, provide electricity to drive motors and lightening requirements, which we generate using steam turbines. Therefore, boiler efficiency directly related to cost of steam and electricity. In industries we generally

Design of Experiments for Reactor Yield Maximization?

1 Comment / Industry / K Mehra

As we know to validate theoretical solution or new product design, we need to conduct actual trials. These experiment trials we conduct to observe the impact of various input variables on output variables. Before implementing the solution on commercial scale, it is better to check them at pilot scale. This way we can avoid any

Liquid Liquid Extraction System Process Calculation

1 Comment / Heterogeneous Stuff / K Mehra

In plants liquid-liquid extraction column is used to separate components using solvent. In liquid-liquid extraction process solute is transferred between solvents. Moreover, both the solvents are insoluble in one another. However, the solvent which contain solute we consider it a feed stream. And, other is solvent stream in which solute transfer takes place. Selection of
